"I am sorry that I left you. I was a coward. I couldn't face the pain of losing you, so I ran away. And then I made myself not feel anything because I didn't want to feel the shame. The problem is that... shame is the one thing that I still felt. Uh... I'm sorry that you went out like that. I should have been there. I am sorry that I named a stupid baseball bat after you. I'm sorry for all the pain that I put you through. I hope that you found someone in the afterlife and that you are screwing your brains out. Well... not really, but... fair is fair. I miss you. I loved the ♥♥♥♥ out of you. And I am gonna do your fighting for you."
—Negan says goodbye to his wife.

Negan Smith (pronounced NEE-gan) is a main character and a former antagonist, as well as a survivor of the outbreak in AMC's The Walking Dead. He was the former leader of the Saviors. He used his authority and resources to subjugate other communities tribute to the Saviors, in exchange for protection against walkers. After a war against the Militia of his formerly subjugated communities, he was defeated, which ended up with Daryl Dixon taking charge of the Saviors, now willing to cooperate with the communities before its disbanding. He was taken as a prisoner to the Alexandria Safe-Zone, receiving a life sentence.

Negan remained imprisoned in Alexandria for seven and a half years, until Gabriel Stokes failed to properly close his cell door, allowing him to escape. After seeing how the world had changed, Negan chose to return to Alexandria and his cell rather than be alone. He has also developed a close bond with Judith Grimes. After saving Judith during a massive blizzard, Negan was allowed to take on a role in the community under supervision.

After accidentally killing Margo while protecting Lydia, and facing a death sentence, Negan is freed from his cell by Carol Peletier, and sent to infiltrate the Whisperers and kill their leader, Alpha. After coming terms with his past, Negan chose to become a full member of Alexandria despite the danger of Maggie Rhee seeking revenge upon him for his earlier actions. He served as the primary antagonist for the second half of Season 6, and for all of Season 7 and Season 8, but has also been present as a recurring antagonist, bordering on anti-hero, since Season 9.
At the last episode of season 10 Negan was finally able to say goodbye to his dead wife Lucille.
